A new type of scene adaptive coder has been developed. It involves a quadtree mean
decomposition of the motion-compensated frame-to-frame difference signal followed by a …

The block-matching motion estimation is the most popular method for motion-compensated
coding of image sequence. A VLSI architecture for implementing a full-search block …

Presents a new motion estimation method for low bit-rate image sequence coding that uses
a hierarchical decomposition of the current image frame to describe scene motion in terms of …

Low power and high performance are the two most important criteria for many signal-
processing system designs, particularly in real-time multimedia applications. There have …

An approach to stereo image compression based on disparity compensation is proposed
and evaluated. The new compression scheme is motivated by the suppression theory in …

Visual pattern image sequence coding (VPISC) is a new digital image sequence (video)
coding process that possesses significant advantages relative to other technologies; in …

Quadtrees are a compact hierarchical method of representation of images. In this paper, we
present a new type of scene adaptive coder which is based on a quadtree mean …

Motion compensation is a very effective process which can be used in video data
compression for increasing the prediction accuracy in inter-frame coding. The conventional …

A summary is presented of a study on two-dimensional linear prediction models for image
sequence processing and its application to change detection and scene coding. The study …

We propose a block-based conditional motion estimation scheme for video compression.
The blocks in a frame are classified as active or inactive based on a threshold and only the …
